Strengths Comparison
Carbon Fiber Polycarbonate Strengths
- Extremely stiff; useful where flex must be minimal
- Surprisingly affordable in some brands
TPU Strengths
- Perfect layer adhesion; extremely impact resistant; nearly indestructible
- Great for combat robots, tactical/rough-use parts
- Rubber-like parts (gaskets, grips, bumpers, wheels)
Considerations
Carbon Fiber Polycarbonate Caveats
- Feeding can be difficult unless spool is close/direct-fed
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
Frequently Asked Questions
Is Carbon Fiber Polycarbonate or TPU better for 3D printing?
TPU is generally rated higher (Tier S) compared to Carbon Fiber Polycarbonate (Tier A). However, the best choice depends on your specific needs: Carbon Fiber Polycarbonate is best for Extremely stiff; useful where flex must be minimal, while TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible.
What are the temperature differences between Carbon Fiber Polycarbonate and TPU?
Carbon Fiber Polycarbonate prints at 270-300°C nozzle / 100-120°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do Carbon Fiber Polycarbonate and TPU need an enclosure?
Carbon Fiber Polycarbonate: required. TPU: not needed.
Which is more beginner-friendly: Carbon Fiber Polycarbonate or TPU?
